PROBLEM TO BE SOLVED: To make foam ejected from a nozzle hole uniform by spreading a foam regulating net on a nozzle hole. SOLUTION: Large and small diameter chemical pistons 16, 17 at low ends of both large and small diameter stems 18, 19 ascend together in the insides of large and small diameter cylinders 4, 6 with ascending of a working member 15. The air passes thorough an open air suction valve 22, a large diameter cylinder 4, the large and small diameter stems 18, 19 with a negative pressure caused by this ascending and also the liquid in a container body passes through the small diameter cylinder 6 and small diameter stem 19 and respectively passes through a foaming member 26, and foam is produced and ejected from the nozzle 20. Since the foam regulating net 28 is spread in the nozzle hole, the foam passed through the spread net 28 passes through the nozzle hole as it is and ejected. Thus, since there is no pressure resistance in the case that foam is produced in an engaged cylinder, turned and ejected from the nozzle 20, foam regulating efficiency can be enhanced. |
